<p>The members of <a class="link" href="pool_options.html" title="Struct pool_options">pool_options</a> comprise a set of constructor options for pool resources. The effect of each option on the pool resource behavior is described below:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p><code class="computeroutput">std::size_t max_blocks_per_chunk</code>: The maximum number of blocks that will be allocated at once from the upstream memory resource to replenish a pool. If the value of <code class="computeroutput">max_blocks_per_chunk</code> is zero or is greater than an implementation-defined limit, that limit is used instead. The implementation may choose to use a smaller value than is specified in this field and may use different values for different pools.</p></li>
<li class="listitem"><p><code class="computeroutput">std::size_t largest_required_pool_block</code>: The largest allocation size that is required to be fulfilled using the pooling mechanism. Attempts to allocate a single block larger than this threshold will be allocated directly from the upstream memory resource. If largest_required_pool_block is zero or is greater than an implementation-defined limit, that limit is used instead. The implementation may choose a pass-through threshold larger than specified in this field. </p></li>
